SALT-CARTRIDGE.

. Specication of Letters Patent. i

Patented Feb. 1'7, 1914.

Application led August 28, 1912. Serial No. 717,449.

To all lwhom it may concern v Be it known that I, PHILIP K. STERN, a citizen of the United States, residing in the cityl of New York, Iin the county and State of New York, have invented certain vnew and useful Improvements in Salt-Cartridges, of which the following is a specification.

My invention in salt cartridges relates to a package containing salt, which is provided with means for protecting thel salt from becoming attacked by moisture. It has more particular reference to packages of this character sealed in of suitable hard cardboard with an exterior wall.

The object of the invention is to provide a salt package or cartridge conducive to sanitation, which, at the same time may be placed upon the market atvsuch a low price,

that, after the contents thereof have become exhausted, the container or ypackage may be thrown away. 4

Another object of my invention is to pro- -vide .a receptacle for the container which may be adapted to the ready insertion and withdrawal of the container' therefrom, while at the same time the whole may be employed as a shaker.

The features of my invention whereby I attain these objects lie in'the construction'.

as disclosed in the drawings hereto attached,

which, when taken withthe correlative appended descriptive matter forms part-of this specification, and the distinct features of novelty are referred to in the claims at the conclusion of the specication. Y

With reference to the drawings: Figure 1 is a sectional elevational view of one of my improved salt cartridges and container on a somewhat enlarged scale. Fig. 2 is a'top plan view thereof. Fig. 3 is a side elevationalv view of oneof my improved cartridges together with a sectional elevational view of a modified form of shaker, and Fig. 4 is a similar view to that of Fig. 1,'illustrating still another modification of the shaker.

In the several figures, similar characters of reference designate like or the same parts wherein A refers to a cartridge or container which is, preferably constructed of paper tubing and is of cylindricalform.

2A designates the bottom cover therefor of yleave an ungummed space l.

a paper 'envelop tion of the disk C to the cap 1A similar material and 1A the top perforated cover which permits the salt contained Within to .escape through a series of perforations a.

To normally provide a paper disk C of a diameter sutilcient to coverthe perforated portion of -the cap 1A, and around the margin thereof, apply an adhesive, such for example as gum or glue, whereby the rim c of this adhesive will be distributed around the edge of the disk C.

Projecting from the disk C is a tab 1C, and

where the same projects from the disk C,

The ap licais e ected by moistening the rim c and applying the disk theretoin a familiar manner. It will be understood that inasmuch as that the disk C is secured merely around the edge to the cap 1A, contact between the remaining portion of the disk and the said cap is obviated, thus moisture in the atmosphere is screened from the cap 1A and the perforations a therein.

In order to screen the moisture from the outer wall of the tube A, I secure an outer tube or label 1a by its opposite ends or edges to the outer annular wall of the cap 1A and bottom 2A respectively, whereby, the same will be disposed as a moisture screen about the salt and tube A leaving therebetween an annular air space 1".

The cartridge entire, consisting of the tube A, end caps lA and2A, end cover or disk C and moisture screen 1a is inserted in a shaker for convenient use comprising an annular shell or tube B, having an integral end 1B, provided with an annular opening b, and a lflanged cover 2B, provided with a close the perforations a, Iv

screw thread 3B, whereby the bottom may f be expeditiously removed for renewing the lcartridges or containers when the same have become exhausted of their salt supply.

In the modification of Fig. 4, I have shown the reverse arrangement for the opening of the shaker B, and in this instance the upper end is rendered removable in lieu v of the bottom. I have also shown in this construction, the upper edge turned in so as to form a sort of counter-sunk opening referred to as 2b. I have furthermore shown a means in this construction of maintaining a Contact between the upper cap lA and the upper end of the shaker which I accomplish by placing a bow or elliptic spring 3b in the bottom of the shaker and placing the container or cart-ridge thereon, whereby the same will be pressed up against the annular edge of the cover 2B of the shaker.

In the construction illustrated in Fig. 3 I provide the spring 3", the ends of which are carried in an annular groove 4B of the cover 2B.

To permit of the exit of the salt through the perfora-tions a, the disk C may be removed by grasping the tab 1C and tearing the former from the end lA of the cartridge, or as an alternative when it is desired to retain the disk C as a moisture screen for the end lA of the cartridge, it may be perforat-ed with a pin or other suitable pointed instrument through perforations a, and to provide an index of location, thedisk C after being assembled and secured to the cap lA is marked over the perforations a by the application of suflicient pressure to the cap 1^ and the disk C in a suitable press.

It will be observed by the above descrip tion of my invention that a simple and inexpensive salt package is provided, having protection against ingress of moisture from the atmosphere, together with a receptacle for protecting the moisture screen against damage as well as a means for preventing the accumulation of salt between the shaker and the container. y

Having fully described my invention, I claim as new and desire to secure by Letters Patent of the U. S.

l. A salt cartridge and shaker comprising, an outer casing of moisture resisting material, having an opening at. one end and closed at the other end thereof, and an inner casing consisting of a tube of paper providedl with flanged caps of paper covering eachend of the tube, a cylindrical screen secured to the flanged portion of each of said caps and surrounding said tube of paper and forming an annular air jacket between said paper tube and screen, and a paper disk provided with a series of perforations, said disk being secured around its edge or'rini portion to the upper surface of the upper cap and having a tab extending therefrom.

2. A salt cartridge and shaker comprising, an inner casing having a top or cover provided with a series of openings for the egress of salt, and an outer casing of moisture resisting material, having an opening at one end and closed at the other end, said outer casing being provided with a countersunk opening in its upper end terminating in an annular depending edge, and a bowshaped spring resting `on the bottom of the outer casing, the upper cent-ral portion of said spring heilig adapted to contact. with the lower surface or bottom of the inner casing and press the inner casing upward so that the t-op thereof will contact with and rest against the said annular depending' edge of the said outer casing.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
